(A) When a customer’s or user’s utility bills are in arrears because of claimed financial difficulties, the customer or user has not defaulted on a previous credit extension, a 90-day credit extension shall be given to the customer or user, upon request to the authorized representative, whereby the customer or user shall pay his or her monthly bill on the basis of the following deferred payment schedule:
(1) First payment at end of 30 days: one-third of the bill in arrears plus monthly current charges;
(2) Second payment at end of 60 days: one-third of the remaining two-thirds of the bill in arrears plus current charges; and
(3) Third payment at end of 90 days: last one-third due on the bill in arrears plus monthly current charges.
(B) If a customer or user, however, defaults on this agreed-upon deferred payment schedule, all service bills in arrears shall be immediately due and payable and no further credit extensions shall be granted that customer or user. A new written notice as specified above in this subchapter shall be sent to the customer or user stating the new service termination date.
